We've seen the mystery Corvette concept (who some dare to believe may be named "Hot Rod") from the upcoming Transformers: Revenge of the Fallen movie three times already. The first photo was a blurry camera phone shot from far away. The second shot was of the folks at Saleen busily painting the new movie star up and making him all silvery-looking. The third shot showed the mystery Transformers Corvette concept and a buddy about to be loaded up to roll out. Now, thanks to an e-mail tipster, we have the fourth and fifth shots as it gets close enough to the camera to see the "GM Design" logo on the rear end. Is it a prototype for a "C7" Corvette? Is it some hot Rodimus action? We guess we'll have to wait and see. (Hat tip to Anonimus Prime!)
